摘要
A method for forming a multi-layered structure includes forming a resin-infused fibrous material (70) by applying a liquid resin component (60) onto the fibrous material (32) being pulled through an injection box (110) such that the fibrous material is partially impregnated and surrounded by the liquid resin component to form a resin-infused fibrous material. The resin-infused fibrous material is then introduced to a first die (130) and partially cured to form a partially-cured fiber-reinforced core material (80). The core material exits the first die to an intermediate region, where a polymer layer (40) is then applied onto at least a portion of the outer profile surface of the core material. The material then enters a second die (140), where the liquid resin component is fully cured to form a fiber-reinforced thermoset core material (30) having the polymer layer adhered thereon within the second die, thus forming the multi-layered structure (20).
